Yes, a 32-bit version should be possible. We will work on it and get back to you soon.

Regarding exposing our network protocol, this a great idea in principle but would require quite a big effort to produce the documentation that describes it in sufficient detail for it to be useful. For example, the bulk of it is TCP; UDP is used for server discovery and time critical transmission. The data that Aerodrums sends to the Aerodrums 3D client is quite "raw" so there are a lot of algorithms that run on the client to convert this is into 3D data that can be displayed. All of the drum kit animation is also computed on the client end. So it is not a simple matter to go from the network traffic to a 3D visualisation. That said, if you have a specific idea for what you had in mind to implement, feel free to PM me and we'll consider it.
